I was in a bit of a panic and still am tbh. The main thing is how easy it is to find resources for any hobby or niche interest on there. It's gonna take a long time for any website to catch up the wealth of resources. I still find myself going "site:reddit.com thing I'm searching for" even though I don't interact with reddit itself too much. That's the thing that will hurt most when it's gone. That and the daily music news/discussions since I like to listen to music.
